Introduction
Johanna Vartiainen is a notable inventor based in Haukipudas, Finland. She has made significant contributions to the field of cognitive radio technology, holding 2 patents that showcase her innovative spirit and technical expertise.
Latest Patents
Her latest patents include a system for monitoring channels in cognitive radio. This invention features a transmitter that selects a free channel from memory for power measurement. A power meter measures the received power from the selected channel, while a detection selector compares this measured power to a previously saved power value. If the power is within a predetermined range, the channel is selected for detection. The system then communicates in the channel if it is detected as unoccupied. Another patent focuses on the localization of narrowband signals. This invention involves forming a sample set from received signals and grouping adjacent samples that exceed a lower reference value. If any of these samples also exceed an upper reference value, it indicates the presence of a narrowband signal.
